Notepad: This puzzle may be solved in Across Lite or the Java applet as a normal crossword. However, since it contains bonus elements that cannot be rendered electronically, we encourage solvers to print out the PDF that is also being offered.

JimH notes:Here's the PDF. There is an especially elegant aspect of this puzzle that shouldn't be missed. When every O inside the die shape is colored in, the spots on each side are properly oriented, but notice that the sides themselves are correctly aligned as well. So, for example, each pair of opposite sides adds up to seven, as they should.
